From super slob to superhuman, Lester Savage completely transformed his body and mind through a whirlwind of research into neuroscience, biology, psychology, anthropology and spirituality. He lived in a Buddhist centre, trained his body to endure sub-zero temperatures and lost over 100lbs. Physically, intellectually and emotionally Lester discovered the key to unlocking true human potential... changing our biochemistry. Science has proven our hunter-gatherer ancestors were given definite biological rewards/feelings for operating within certain evolutionary parameters. These rewards/feelings gave them the physical and mental strength to do incredible things. It made them happier, stronger, braver and healthier. To us, they would seem like superhumans. Despite living in the best era of human history, we need only briefly look around to see that something is terribly wrong. Depression and anxiety is dramatically on the rise, obesity is considered the new epidemic, and although our cities are filled with millions of people it has never been so easy to feel completely alone. It's obvious that western culture isn't working for our species. By moving away from the evolutionary parameters most of us have stopped getting this biological reward. We now know that the reward experienced by our ancestors was a biochemical response in the brain and body - a series of neurotransmitters that act as a catalyst for strong mental and physical health. Thankfully we don't need to return to a primitive style of living to also experience these feelings; by making small lifestyle changes and working within the correct evolutionary parameters we can begin to produce a consistent flow of these neurotransmitters too. The result? We become superhuman. We become biochemically sober.
